1188 = πr²h
For the formula to solve for h, you have to change the equation to:
h = 1188/πr²
which is just moving h to the left side of the equation, and moving v(in this case 1188) to the right side.
because h was multiplied to the original equation, switching sides in an equation makes its replacement(1188) into a devision. (if you move a number across the = sign, the number will become the opposite of itself.)
Since you don't know the radius, you can't simplify this equation.
The answer is h = 1188/πr²
